To understand opportunities and challenges associated with adopting and implementing MR-Linac into routine care, we used the Non-adoption, Abandonment, Scale-up, Spread and Sustainability (NASSS) framework of new healthcare technologies. The NASSS framework addresses challenges to implementation of technologies in healthcare organizations by assessing seven domains: the clinical condition, the technology to be adopted, the value proposition, the adopter system (patient, lay caregivers, individual technology user and other staff), the organization, the wider institutional and social context and the interactions between and adaptation of these domains for technology development over time. Between November 2018 and March 2019, we conducted 43 semi- structured interviews with professionals in prostate cancer treatment, hospital directors, division managers, patients, payers (insurers) and industry. We included academic and non-academic hospitals to explore implementation differences and to limit selection bias. To increase reliability, resultant codes were validated by a second reviewer. We also discussed whether the empirical data matched the framework, ensuring that the results were all classified within the domains. Results Reported opportunities included an attractive, unavoidable development in radiation technology with expected better patient outcomes, professional development for radiation oncologists, physicists and radiation technologists, profiling hospital quality and potential economic benefits for hospitals and payers. Respondents indicated also challenges, including the lack of clinical evidence of effectiveness, technological complexities, large financial, organizational and operational investments, need for additional staffing and training, patient referral discussions and presence of professional silos. Although technological developments may reduce its technical hurdles, it remains to request rapid learning. Conclusion MR-Linac is perceived as a promising innovation, with the potential to improve patient outcomes and advance the field of radiation therapy. Adopting MR-linac also allows professional growth and potential economic benefits. However, our research also revealed technical, operational and educational challenges. Clinical outcome evaluation remains crucial to prove claims of clinical superiority, which is necessary for this technology to be more widely accepted by professionals and payers.

Conclusion The combination of the future demand figures from the 2015 IMRT report and the Malthus model has produced the regional variations in IMRT demand. The heat map of the comparison of recorded IMRT delivery data to the local- level demand, highlights regions within England which may be under providing, or over providing, IMRT. These areas should be investigated in detail to identify the reasons for these differences. There may be non-service factors driving the differences, such as data and recording inaccuracies, incidence fluctuations or comorbidities. These are factors which are not currently included in the Malthus model.

MR-Linac allows high precision radiation therapy under real-time visualization. This approach has evident benefits in prostate cancer radiotherapy, including dose escalation and sparing of healthy tissues. Opportunities and challenges in adopting and implementing MR-Linac for prostate cancer were explored. Material and Methods
